i have a '03 7.3 with some bad glow plugs. it's too freaking cold outside right now to change them out. it starts after torturing the starter for 30 seconds and then runs like a bag of **** for a few minutes. it starts fine if i plug it in but i keep forgetting to plug it in the night before or unplug it before driving away.

has anyone tried jumping a wire from the control side of the glow plug relay to the control side of the intake heater relay? does anyone see a problem with this? is this even worth doing due to the possible lack of heat that heater actually puts out?

I disagree with what he said. Last winter I had glow plug relay problems and one time I did jumper the wire for the grid heater while someone cranked it for me and it fired right up. I can't say for sure in extreme temps that it would be the same but it worked great that time for me.

The mid 90's cummins engines only have grid heaters and they start up in cold temps too. I think it would be worth a test to see how it works out.

Might work in a pinch but I would put my efforts and money into fixxing the glow plugs properly. And then delete the AIH. I put a plug in the hole with a tapped fitting for my boost gauge on my yellow dually.
